Mageia forum

Hello,

I tried to install Mageia 6 as new instance instead of Mageia 5, but after boot loader it comes to emergency mode saying

Code: Select all

I/O adress already in use

and

Code: Select all

fsck failed with error code 4

and

Code: Select all

failed to start faile system check

why?

Probably because one of the filesystems is defective?

how to check file system?

With fsck

hmm... the output for fsck -A is

Code: Select all

/dev/sda2 is mounted

what to do?

Fsck don't support checks on mounted partitions/filesystems.

It does, but you should only do a readonly check on mounted filesystems, and even then fsck will warn you that this will produce unreliable results.

You need to unmount /dev/sda2 and then run fsck on it, either from the rescue shell or maybe by booting some linux live boot media.
